Detection of "hot spots" in electrical and mechanical applications, boiler and furnace refractory voids, and other process applications upon request. These services are provided by experienced, certified thermographers.
Motor Circuit Evaluation is an off-line type of testing that requires that the motor be de-energized and is typically performed during down periods. It is extremely useful in providing indicators of stator winding and insulation system health. An off-line test for motors that yields inductive balance, resistive balance, resistance and capacitance to ground as a trendable indicator of motor stator health. Also useful in diagnosis of faulty or broken rotor bars, eccentricity, and defective or deteriorating motor connections.
On-line motor testing is extremely useful in assessing rotor condition in induction motors as tested under normal operating conditions. This is accomplished through spectral analysis at the first and fifth harmonics of line frequency. This testing also yields current imbalance expressed as a percentage under load, and impedance imbalance as a trendable measure of stator condition.
Power quality assessment, including measures of total harmonic distortion and crest factor, is performed in those cases where voltage and current signals (PTs and CTs on any testing over 600 volts) are both available. This type of testing also offers the advantage of being non-intrusive to production operations.
Offered as a service in which programs are set up from "scratch" including establishing routes, monitoring frequencies, alarm limits, etc., or as a supplement to your existing vibration / testing program. Balancing and alignment services offered on a per call basis. Services performed by a Level 2 certified vibration analyst with 15+ years field experience

Balancing and alignment services offered on a per call basis. Services performed by experienced, certified vibration analysts.
Offered for mechanical applications such as high and low speed bearings, air / gas leaks, steam traps, etc. Also extremely useful in medium to high voltage electrical applications for arcing, tracking, and corona detection where safety issues prohibit the opening of electrical enclosures. This type of testing has been proven to be valuable in both short term trouble-shooting and longer term (results trending) applications.
In this type of testing, multiple technologies are applied to accurately assess current machine condition. This method of testing has been proven to be valuable in both short and longer term (results trending) applications.
Offered to ASNT-TC-1A specifications for Levels 1 and 2 thermographers. Also offered for basic AC/DC motor theory and testing technologies.
